There is a solution. You can stick a QR Code around your house, so your guests (and you) can just scan it with an Android phone. It's a secure shortcut with your password hidden inside it. When you need it, you scan the QR Code instead of typing in your password.

If you think you don't know what a QR Code is, you do. It's that odd-looking box that's filled with smaller boxes, which you may have seen people scanning for discounts at the supermarket.

QR codes are super simple to use and, with the Cool Site QR4, super simple to create. Click on the blue Cool Site box below.

Then you'll need just three pieces of information, which you can get from your Internet provider. Or, follow along here:

First, look at the back of your modem for "SSID." It might be shown as something like, "Wi-Fi Network Name (SSID)." It'll be about a dozen numbers and letters; type those in where it says SSID on QR4's Code Generator page.

Second, type in your password. It might be "Administrator." If you don't know, call your Internet provider. Third, choose your secure network type; the site defaults to WEP, but you may have WPA. If you don't know, ask your Internet provider.

Click here to generate the WiFi QR Code. You now have your own, very cool QR Code. Print it out, and post it around the house. The next time you hear, "What's the Wi-Fi password?" Just yell back, "Scan it."
